Quality practice:
The details of rework required as a result of non-conformances are documented on each project.
As much as we might strive for zero defects during construction, non-conformances will occur, and when they do, the solution often leads to unexpected rework. Rework is an important measure of the cost of quality, and equally, provides a way to identify and rectify issues that are at the root of poor quality.
There are numerous examples that demonstrate the importance of capturing the details surrounding the quality issues that are encountered during construction. The bottom line is that we wish to identify causes so that they can be reduced or avoided in future work.
So when the concrete does not meet strength requirements and the sound of jackhammers is imminent, we should not forget the opportunity to capture the details of why. The most effective approaches to capturing causes are in the form of basic checklists that help to organize the reasons why, such as, an error in design documents or an issue with supplied materials. This information can then be aggregated and help support lessons learned programs and process improvement activities.
Organizations such as the Construction Industry Institute and the Construction Owners of Alberta have developed extensive programs to support the reduction of rework in industrial construction environments. They all relay on the first step of capturing the “why”.

ABOUT THE PERFORMANCE BENCHMARKING TOOL
The free Performance Benchmarking Self-Assessment Tool is designed to assist construction and maintenance employers in measuring their organization in relation to a specific set of recognized best practices. In addition, you will be able to compare your organization’s efforts against other construction and maintenance employers. From the results of the self-assessment tool you will also be able to identify areas for continuous improvement.
The self-assessment tool is designed to be completed either individually by a member of your management team or in a collaborative setting. Consider bringing your leaders/managers together to work through the tool and take time to discuss the perspectives of each group member.
This initiative is supported by the National Research Council of Canada Industrial Research Assistance Program (NRC IRAP).
